2 Pack A1 Mini/A1 Hotend Print Head Hot End Kit Extruder Upgrade High-Temperature 0.4MM Hardened Steel Nozzle Replacement with 4PCS Silicone Cover Sock for Bambu Lab 3D Printer Accessories

These HotEnds are a PERFECT replacement...! some of the best replacement hardened nozzles I've found for 3D printing. The hotends are a perfect fit and the results after using are just what I was hoping for. I have used the hardened 0.4mm replacement and now i am planning to order the rest of the sizes for my Bambu A1. Could not be happier with this company's customer service as well. Also, delivery was very quick.

We run a small print farm and these are the go to for us. High build quality. Never had a problem and they install just like factory. Hardened nozzles run great. Great value for the money.

Needed to replace old head the was damaged. This was a great price and it worked as well as the original. Perfect fit for my bambu a1 mini.

Have not been running this very long but I’ve definitely seen some improvement

Used on A1 mini. Easy to replace, no issues when comparing to factory component. Printed both TPU and PLA since switching.

Had no issues with my OG Bambu hot ends. Threw one of these ones on today. NO GO. Nozzle clogged instantly and gave feeding issues. Feed kept clicking like a clog or jam even though filament was barely coming out. Did some trouble shooting, put the OG Bambu back in. Worked fine. Put one of these hot ends back on and again issues. So it’s the hot ends not me. I don’t recommend. For a few buckaroos more I’m going to get the Bambu brand. I learned my lesson.

Works great! Easy to install and prints great.

The fit is good and my first few prints with them have gone well. I had issues jamming on the 0.2 hotends before and I am hoping that these might be less prone to that issue, or at least easier to clean. So far very happy with the results.
